Samsung Kies is one of the worst pieces of software I think I've ever come across. I had to install it to upgrade my mother's SGS, I was astonished by how much it clogged up my system (3 separate autorun entries, 2 services), and how unbearably slow it was.

@fredley Kies Mini is a lot better, just a small standalone app.

Sounds like there's something funny with either your USB cable, the charger or the socket on your phone that's causing it to detect it as a full PC connection, rather than just a dumb charger.

You should be able to get rid of that prompt for the moment by going into Settings -> Wireless and Network -> USB Settings and selecting the Mass Storage mode rather than the Samsung Kies mode.

However you really ought to try with another charger and cable to see if that fixes the actual problem, pure-charger cables shouldn't be detected as a PC, the signal on the cable is different and the phone should detect that.

I don't have USB Settings under Wireless and Network.

@ripper sorry you must be running a different update then, I know Samsung have moved that setting around at times. Have a look under the other headings in Settings to see if you can see the USB settings, I think it might have been under the SD Card and phone settings in the past too?

They seem to have removed this option completely for S4 Active.
One keeps wondering why Samsung chose to use Kies, which slows down file transfer substantially and, moreover, may do weird things like changing the photo date of image files when moved across the device's folders...
